How does one prove that all humans see the same colors? Is it possible?

Okay, put on your scientific—and potentially philosophic—thinking caps. This is one of these questions I wondered since I was a kid, and am curious to see what methods, if any, can be used to answer it.
At a very young age, we are all taught that this color:
is blue and that this color is:
Our senses appear attenuated in such a way that we all are aware of what colors match well, and what colors clash. Our theories of color apply, it seems, no matter how we perceive the world, but ... can we prove that all of us see the same colors? How do I know that what I know as "green" is the same color in your eyes? For all I know, my "blue" may look like your "pink".
This isn't so much a question of "do we see the same colors?", rather I wonder if we have techniques that we could use to prove that we do. Colors being so intimately tied to the brain, I cannot think of any experiment we could perform to test the theory.
